In PC11.52 under edit loadtest when adding scripts to a scenario in the test designer page, nothing happens. No script gets added to groups. This behavior works in specific browser versions and fails in others. For example: it works on IE9 but fails on IE10

By default myPC page opens in a problematic browser mode and document Mode.

After adding the PC Server url to Internet Explorer (IE) list of sites to open in ‘compatibility mode’, the site opens well on IE10 machines

So to get this working:

Need to add the PCS url to list of sites to open in ‘compatibility mode’. Then change document mode to “IE7 standards” (using F12)
